Product Description

Thermal Cut-Off Kit Specifications

The thermal cut-off (Dryer Thermal Cut-Off Fuse Kit, Dryer Thermal Cut-Off Kit) prevents the dryer from overheating when the dryer high limit thermostat fails in a closed circuit condition. This part fails when the heater housing does not have adequate airflow through it; this is normally caused by restriction in the exhaust vent, plugged lint screen, or broken blower wheel. If this part fails, the dryer may not produce any heat. This kit includes one high-limit thermostat with a limit of 250 degrees Fahrenheit, and one thermal cut-off fuse (309 degrees), jumper wires, and new female spade terminals. Both components are mounted on the heater housing, and measure approximately 2 inches long and 1.5 inches wide each. This kit comes in silver and is constructed of metal.

The dryer took at least 3 rounds to dry light clothes and 4-5 for towels.
This was my second time making repairs. The only difference this time I replaced all parts from top to bottom. When I pulled the heating element out only one coil was working the others had burned out. It was easy to do and the videos on the site are very helpful and informative. I followed the steps and if I thought I missed a step I replayed it again. I am a woman and found it very easy and not at all intimidating at all. I am going to hopefully have it for another 10 yrs. You guys keep up the good work.

Dryer was not heating in timed mode. It was heating in other modes. Thermal cut-off broke in testing.
1/4 inch nut driver to remove panel back cover(6), timer unit(2), and cut-off(1).
Pliers to aid in removing single wires from components.
Most wires on timer were in position specific connectors.

Dryer runs, but won't heat.
First only replaced the high temp cut off switch which allowed the element to heat. However, after one heat cycle the switch would not reset. Then changed the thermostat (included in the kit). After tapping the cut off switch lightly to manually reset it, the dryer ran perfectly. Moral of the story: always change all parts included with a repair kit!

Dryer not drying items after one cycle, although dryer was getting hot.
Followed the video instructions that I was directed to through this site. The time it took me includes the time I used to vacuum out the back of the dryer and remove lint build up. The repair was very easy since the video provides all the information you need in an easy to follow format. I used my cell phone and paused when I needed to. Great site, great access to parts and great service. My parts were delivered in 2 days!

NO HEAT
I highly recommend using a multi-meter to test for continuity on the thermistors and the heating element. It will likely save you a lot of time and you can replace the correct part the first time. I found the high limit thermostat to be open. Also note that if you find the same part open, it is most always caused by another part failure or the dryer vent to be clogged up with lint. I also cleaned out the lint chamber which was in pretty bad shape and likely caused my failure. But, the parts were not expensive and were replaced while I was doing the trouble shooting. The video is excellent and if followed all will turn out ok. This is my third different appliance repair, and the parts are always in stock, the standard shipping was 7 days, and everything you need is provided.

My dryer is having trouble heating up, or heating at all. Based on what your site is saying it may be the thermostat with the thermal fuse. Does that sound right, and is this what I need to make the repair?

Okay, i have now replaced thermal fuse and internal bias thermostat. Dryer runs with much heat and shuts off as expected, at end of cycle. Just for diagnostic purposes, i ran the dryer on the air only cycle/no heat. However, the dryer still producing heat. Is this normal? I suspect it is not, do i need to replace other parts as well. Thank you for your help. All the symptoms i was viewing were describing no heat, and it appears as if i have too much heat. Thanks again.
For model number IED4400VQ1

Hello Steve, thank you for your question. I would recommend replacing the Thermal Cut-Off Kit part number 279816. The thermal cut-off turns off the heating component when the dryer overheats, ensuring there is a consistent level of heat at all times. If the unit isn't cycling off properly, the unit will get too hot. I hope this helps!

Hello. For the past two weeks when running my dryer it shuts off after 5 mins. As of 08-21-17 it will not turning on at all. Could this part fix this issue? Thank you in advance.
For model number GEQ8858EQ0
PartSelect logo
Hi Dion, Thank you for the great question. The first part we suggest you replace is the Thermal Fuse. This thermal fuse is designed for use in dryers. It is a safety mechanism that stops the flow of electricity to the heating element when a dryer overheats. When this fuse is faulty, your dryer will not start or it will not heat properly and shuts off to soon. This is a one-time fuse, meaning it cannot be re-set, It must be replaced. Hope this helps!

I am getting no heat but i have continuity and the heating coils have voltage.
PartSelect logo
Hi Micha, we recommend first disconnecting the wires to the heater and checking them for 240 volts across both. If you do not have the 240, you need to find where you are losing the rest. I hope this helps.

My Whirlpool dryer does not heat. I found that there was no continuity between the two connectors on the thermal cut off. Would this mean the this part is bad?
For model number LER4600PQ1

Hi Kim, Thank you for your question. Yes, you would have to replace that part if there is no continuity. Good luck with your repair.

What is wiring order for this repair?
PartSelect logo
Hello Jonathan, the order of the wiring from your motor should go to the heater, then to the thermal cut off, and from there to the high limit, and then to the timer. Please let us know if you have any further questions.

My dryer heats up in less than a minute. It is hot enough to burn your fingers on the rear of the drum. Changing the heat setting does not appear to do anything. Where do I start, and how can I test the components in question? Thank you!
For model number WED4800BQ1
PartSelect logo
Hello Larry, Thanks for your question. You will want a multimeter to test a few different internal parts. Replace any that do not show electrical continuity. Also be sure to clean out the venting if that is clogged. Test the internal-bias thermostat, the thermal fuse, the high-limit thermostat, and the heating element. Visually inspect the belt as well for any signs of wear and tear. I hope this helps.

I have an Admiral electric dryer, aed4475tq1. Lately on autodry, it mostly dries the cloths but then i have to use the 20 30 time dry to finish drying the cloths. Basically, the dryer is shutting off just a little too early on autodry. I don't think this dryer has a moisture sensor to clean. Ventilation is good and there is no build up of lint internally or on the filter.
For model number AED4475TQ1
PartSelect logo
Hello Brian, thank you for your question. The issue is most likely with a thermostat. There are a few thermostats in the unit. With a multimeter, these parts can be tested very easily. The parts you will want to check are Thermostat, Internal-Bias Part Number: WP3387134, Thermal Cut-Off Kit Part Number: 279816 and Thermostat, High Limit 221 F ( Part Number: WP3977767. Set your multimeter to the R X 1 setting. Take each of your meter's probes and touch one to each terminal. You are testing for continuity, and you should receive a reading of either zero or infinity. At room temperature, testing the thermostat should produce a reading of zero. But if a thermostat is tested when it is heated to its limit, a reading of infinity should be produced. We strongly recommend that you test your thermostat at room temperature. If the test you conduct with your thermostat does not produce these results, then you should replace the component. I hope this helps. Thank you and have a great day!

Our dryer has plenty of heat and the drum seems to be rotating, but the clothes won't dry. What would you recommend? Thanks!
For model number len2000pw1

Hello Wes, Thank you for your inquiry. We would recommend checking the following parts to fix your issue: blower wheel, moisture sensor, lint filter, drum seal, lint chute seal, and front seal. Also make sure that the air flow is not constricted in any way. Hope this helps!
